IMPROVEMENT IN WIND-WHEELS.

Specification forming part of Letters Patent No; 2,675, dated June 18, 1842.

`drawings of the same, making part of this specification.

Figure 1 is a verticaVsection at the ddtted line x of Fig. 2. tion at the dotted line o o of Fig. 1. a perspective view of the windmill.

Similar' letters refer to corresponding parts.

This windmill consists of the following combination of parts: The frame for containing and supporting the wheels may be made in the usual manner-square, polygonal, or round. A vvertical shaft S is placed in the center of the frame, turning in a step or oilcup fixed in the center of the intersection of the cross-arms of a revolving wheel of concentrating sails, hereinafter described, and in a box in the center of one of the caps of the frame and extending above the top a convenient distance, on which there is a cog-Wheel D or pulley geared to the machine, to be propelled in the usual manner. AWheel A',con sisting of four segmentlarms ct, Fig. 2, and four wings C, is formed on the lower half of said shaft S, said arms a extending horizontally from said shaft or extending from the peripheries of horizontal circular plates R, fixed on the shaft S, as represented in the drawings, Fig. 2, to which the sails C are fixed in the usual manner, extending from the outer extremities toward the shaft to within a short distance therefrom. A similar wheel A2 is formed on the upper half of said shaft of the same diameter and resting upon the top of thev last-described wheel, with its wings C2v arranged over the center of the spaces between the Wings C of the lower wheel A so that the wings of the two wheels shall not pass the concentrating guides B2, hereinafter described, at the same time. A third revolv- Fig. 2 is a horizontal sec- Fig. 3 is ing Wheel B encircles the aforesaid center wheels A A?, and revolves around them in the same direction and on the shaft S, the circular space in the center of the same being larger than the outer diameter of the center wheels A A2 revolving within the same, having its wings B2 longer than the combined wings of the two center Wheels Ay A2 and of proportionate width, fastened at top and botL tom to segment-arms B3, Fig. 3, secured obliquely to fourhorizontal arms F, crossed at right angles and perforated` in the center of their intersection with circular apertures "through which the aforesaid shaft S passes,

and on which the last-mentioned Wheel B revolves, having the outer extremities of said arms F connected by ,four parallel vertical rods F3, the chords of the arcs of the aforesaid sails forming an angle of about fortyive degrees with the radiating arms F, to which the segments areu secured and to which the sails are made fast, said sails performing the double office of propellers and concentrating-guides, propelling the larger wheel, and at thesame time guiding and concentrating the currents of wind to and against the sails of the small or center wheels,'and therefore may be termed concentrating -guides. These guides may be made stationary by fastening the arms F to the frame of the wheel, (not shown in the drawings,) in which position they would serve the part of concentrating-guides only; but when they revolve the power of the large w-heel is added to that of the small wheels, and is conveyed. to the machinery to be propelled by having a hollow hub H xed to the arms at the intersection thereof, and around which is passed a band leading to the machinery to be propelled, orl

the power may be conveyed by means of cogged gearing and in any convenient Way. In the center of the intersection of the lower arms F is fixed an inverted conical point I,

projecting downward into a step or oil-cup J,u

fixed on one of the sills or bed-pieces K of the frame in which it turns.

, What I claim as myinvention, and which I desire to secure by Letters Patent, is-

The combination of the revolving concentrating guides with the center revolving wheels, as before described.
